Did you read what I wrote ? ] If the disk-driver has a 4k drive, or suspects it has a 4k drive ( ] these properties are advisory only), it should announce that with ] the stripe* properties on its GEOM provider. notice "suspects" ? It would be entirely reasonable for the driver to suspect all drives larger than some N GB to be 4k drives. But the information has to flow up from the driver, so that intermediate GEOM classes can adjust the two stripe-properties according to what they do. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 phk_at_FreeBSD.ORG | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence.Received on Mon Dec 05 2011 - 18:37:42 UTC
